Doubleclick exit not showing

So I’m using export as Doubleclick DCM. I have a button with on mouse click, exit.
But when I upload to doubleclick it’s showing the exit is missing.
“You uploaded the wrong number of assets with Enabler components for this creative. The creative must have exactly 1 asset(s) with Enabler.”

Any advice would be very appreciated. Thank You

I saw someone else deleted and reinstalled the scripts. That worked for me.

Can you clarify what you did? Did you already have some enabler code in the <head> area of your document?
